AI Technical Summary
Traditional cooling methods in continuous casting processes suffer from uneven cooling, high energy consumption, and short equipment lifespan, making it difficult to effectively suppress surface cracks in the billet during the straightening section.
A device based on phase change cold storage roller sleeve is adopted. By embedding a honeycomb silicon nitride ceramic container inside the roller sleeve shell and filling it with paraffin-based composite phase change material, combined with a spiral channel and temperature control module, uniform cooling and thermal stress management are achieved, reducing the temperature gradient in the contact area of the billet.
It significantly reduces the surface crack rate of cast billets, improves product quality, saves water and energy, extends equipment life, and reduces maintenance frequency and costs.
